Link roundups are collections of links to articles, blog posts, and other types of content that are related to a specific topic or theme. These collections are typically compiled by a single individual or organization and shared with their audience on a regular basis, such as daily or weekly. Link roundups are a great way to stay up-to-date on the latest news and developments within a particular field or industry, as well as to discover new content that you might not have come across otherwise. Some popular examples of link roundups include the Skimm, the Morning Brew, and the Daily Skimm.
